INTEGRATED PEST MANAGEMENT IN PADDY

INTEGRATED PEST MANAGEMENT IN PADDY

Among the food grains paddy occupies fore most status in human food requirements. Paddy is grown under different agro-climatic (Upland, Low land &Rained) conditions and the crop is damaged by more then 100 sp of insect pests. This pest causes enormous grain yield losses, which may vary from 20-50% if not protected, India losses 30% yield in rice every year. It is most important staple food of about 65% of Indian population.

IPM (Integrated Pest Management)

IPM is a system that in the context of the associated environment and the population dynamics of pest species, utilizes all suitable techniques and methods in as compatible a manner as possible and maintains the pest populations at level below those causing economic injury.

WHY IPM?

To minimize the indiscriminate and judicious use of chemicals, insecticides and pesticides, It was realized later that many chemicals were not biologically degradable and they not only persisted in the environment but also become concentrated through the food chains. IPM has been formulated as principle of plant protection in over all crop protection programmes under the National Agriculture policy of the Govt. of India.

More than two dozens of insect pest have been recorded to infest rice crop. These pests do not appear regularly and cause varying degree of losses to rice in different stages in different parts of the country. Management of the pests are given below.
